coarsely

the adverb 'coarsely' is formed from the adjective 'coarse', which entered english in the late middle period. its origins are somewhat obscure but it is generally traced to the phrase 'in course', implying something ordinary or of the common run, not fine or special. the semantic journey moved from 'ordinary' to 'lacking refinement' in texture, manners, or quality. the addition of the old english adverbial suffix '-ly' creates a word that describes the manner in which an action is performed—roughly, without finesse, or with large granularity.

Structure: coarse (rough) + ly (adverb suffix) coarse (from middle english 'cors', meaning ordinary or of inferior quality, likely from a low germanic source related to dutch 'koers' and german 'kurs', meaning course or direction). ly (from old english '-līċe', an adverbial suffix forming adverbs from adjectives).
